Is this the desired/planned behavior? Wouldn't it be more *correct* if we refuse any further connections just like nc(netcat) does, when not in brokering/keep-open/chat modes?Yes, it sounds like Ncat should close its socket after accepting its first connection. Would you write a test for how it's supposed to work? David Fifield
Should closing the socket take effect in case of --max-conns also? Or allow just the number of connections specified and then close as soon as that number is achieved? Eg. from the man page for context: -- Bind a shell to TCP port 8081, limit access to hosts on a local network and limit the maximum number of simultaneous connections to three ncat --exec “/bin/bash” --max-conns 3 --allow 192.168.0.0/24 -l 8081 --- The above examples doesn't specify --keep-open.
